There are further clinical trials under current investigation regarding treatments for hypermethylation as well as alternate tumor suppression therapies that include prevention of tissue hyperplasia, tumor development, or metastatic spread of tumors.[3] The team working with Wajed have investigated neoplastic tissue methylation in order to one day identify early treatment options for gene modification that can silence the tumor suppressor gene.[4] In addition to DNA methylation, other epigenetic modifications like histone deacetylation or chromatin-binding proteins can prevent DNA polymerase from effectively transcribing desired sequences, such as ones containing tumor suppressor genes.[citation needed]
